Cloudera Quickstart VM to run python mapreduce scripts.

I'm new to the Cloudera world. I have setup the Cloudera Quickstart VM and it looks good. I have written some mapreduce jobs in python and I have those scripts and input files.

How can I run my python scripts in Clouder Quickstart VM? Is there any tutorial or step by step instructions?

Once I test this in my Cloudera Quickstart VM, I want to set up a 3 to 5 node Cloudera Cluster and run the job using multiple nodes however all my scripts are are written in python. I have been looking for material to help how it can be done on a cloudera cluster but so far I had no luck.
